[PMID: 38864503 DOI: 10.1002/ncp.11160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Revised: 04/30/2024] [Accepted: 05/03/2024] [Indexed: 06/13/2024] Open
Abstract
BACKGROUND Refeeding syndrome (RFS) is a life-threatening metabolic derangement occurring when nutrition is reintroduced after prolonged starvation. Limited data exist regarding RFS prevalence, risk factors, and outcome, particularly in critically ill patients. METHODS A retrospective cohort study was conducted in a medical intensive care unit from June 2018 to August 2020. RFS diagnostic criteria from the National Institute for Health and Care Excellence (NICE) and the American Society for Parenteral and Enteral Nutrition (ASPEN) were used. The primary outcome was 30-day mortality. RESULTS Among 216 patients, RFS was diagnosed in 22.7% and 27.3% of patients per the NICE and ASPEN criteria, respectively. There was no significant difference in 30-day mortality between patients with and without RFS (22/59 [37.3%] vs 53/157 [33.8%]; P = 0.627). Independent predictors of RFS were malignancy (odds ratio [OR] = 2.09; 95% CI = 1.06-4.15; P = 0.035), septic shock (OR = 2.26; 95% CI = 1.17-4.39; P = 0.016), and high NICE RFS risk classification (OR = 2.52; 95% CI = 1.20-5.31; P = 0.015). Factors associated with reduced RFS risk were Sequential Organ Failure Assessment (SOFA) scores >12 (OR = 0.45; 95% CI = 0.23-0.88; P = 0.020) and high-dose vasopressor treatment (OR = 0.34; 95% CI = 0.14-0.79; P = 0.012). CONCLUSION RFS affected one-fourth of the critically ill patients but did not significantly impact 30-day mortality. Malignancy, septic shock, and high NICE RFS risk classification were positively associated with RFS, whereas high SOFA scores and extensive vasopressor use were linked to decreased risk.

Abstract
Previous studies have successfully predicted overweight status by applying deep learning to 12-lead electrocardiogram (ECG); however, models for predicting underweight status remain unexplored. Here, we assessed the feasibility of deep learning in predicting extremely low body weight using 12-lead ECGs, thereby investigating the prediction rationale for highlighting the parts of ECGs that are associated with extremely low body weight. Using records of inpatients predominantly with anorexia nervosa, we trained a convolutional neural network (CNN) that inputs a 12-lead ECG and outputs a binary prediction of whether body mass index is ≤ 12.6 kg/m2. This threshold was identified in a previous study as the optimal cutoff point for predicting the onset of refeeding syndrome. The CNN model achieved an area under the receiver operating characteristic curve of 0.807 (95% confidence interval, 0.745-0.869) on the test dataset. The gradient-weighted class activation map showed that the model focused on QRS waves. A negative correlation with the prediction scores was observed for QRS voltage. These results suggest that deep learning is feasible for predicting extremely low body weight using 12-lead ECGs, and several ECG features, such as lower QRS voltage, may be associated with extremely low body weight in patients with anorexia nervosa.

JPEN J Parenter Enteral Nutr 2022; 46:1859-1866. [PMID: 35274317 PMCID: PMC9464262 DOI: 10.1002/jpen.2368] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Revised: 02/11/2022] [Accepted: 02/28/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND Until recently, refeeding syndrome (RFS) has lacked standardized diagnostic criteria. This study sought to (1) determine whether RFS, as operationalized in the 2020 American Society for Parenteral and Enteral Nutrition (ASPEN) guideline definition, is associated with adverse clinical outcomes and (2) identify key risk factors for RFS. METHODS In this retrospective cohort study, adults hospitalized from 2015 to 2019 were included if they were ordered for enteral feeding during hospitalization. Data were collected for up to 30 days, and RFS was operationalized as per the ASPEN 2020 guidelines as a ≥10% (corresponding to mild RFS), ≥25% (moderate), and ≥50% (severe) decline in prefeeding serum phosphorus, magnesium, or potassium. The mortality associated with RFS was assessed, and risk factors for RFS were identified using multivariable logistic regression modeling. RESULTS Of 3854 participants, 3480 (90%) developed mild RFS. Thirty-day mortality was higher in those without mild RFS (24%) than in those with mild RFS (18%) (P < 0.01). When RFS was reoperationalized as a 50% decline in electrolytes, 25% of patients developed RFS with a 20% 30-day mortality. Risk factors for development of RFS included renal failure, elevated creatinine, and low platelets; additionally, prefeeding serum phosphorus level was strongly associated with development of RFS (adjusted odds ratio, 6.09; 95% confidence interval, 4.95-7.49 for those in the highest tertile of prefeeding phosphorus compared with the lowest). CONCLUSION The ASPEN operationalization of RFS as a decline in baseline electrolyte values was not associated with death. Prefeeding serum phosphorus level strongly predicted severe RFS.

The Performances of SNAQ, GLIM, mNICE, and ASPEN for Identification of Neurocritically Ill Patients at High Risk of Developing Refeeding Syndrome. Nutrients 2022; 14:nu14194032. [PMID: 36235685 PMCID: PMC9572145 DOI: 10.3390/nu14194032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 09/21/2022] [Accepted: 09/23/2022] [Indexed: 11/17/2022] Open
Abstract
We previously found that neurocritically ill patients are prone to refeeding syndrome (RFS), a potentially life-threatening complication. However, there is no unified or validated consensus on the screening tool for RFS so far. We aimed to validate and compare the performance of four screening tools for RFS in neurocritically ill patients. We conducted a single-center, observational, retrospective cohort study among neurocritically ill adult patients who were admitted to the neurocritical care unit (NCU), and who received enteral nutrition for 72 h or longer. They were scored on the Short Nutritional Assessment Questionnaire (SNAQ), the Global Leadership Initiative on Malnutrition (GLIM), the modified criteria of the Britain’s National Institute for Health and Care Excellence (mNICE), and ASPEN Consensus Recommendations for Refeeding Syndrome (ASPEN) scales to predict RFS risk via admission data. The performance of each scale in predicting RFS was evaluated. Logistic regression analysis was used to identify the independent risk factors for RFS, and they were added to the above scales to strengthen the identification of RFS. Of the 478 patients included, 84 (17.57%) developed RFS. The sensitivity of the SNAQ and GLIM was only 20.2% (12.6–30.7%), although they had excellent specificities of 84.8% (80.8–88.1%) and 86.0% (82.1–89.2%), respectively; mNICE predicted RFS with a sensitivity of 48.8% (37.8–59.9%) and a specificity of 65.0% (60.0–69.9%); ASPEN had the highest Youden index, with a sensitivity and specificity of 53.6% (42.4–64.4%) and 64.7% (59.8–69.4%), respectively. The Area Under the receiver operating characteristic Curves (AUC) of SNAQ, GLIM, mNICE, and ASPEN to predict RFS were 0.516 (0.470–0.561), 0.533 (0.487–0.579), 0.568 (0.522–0.613), and 0.597 (0.551–0.641), respectively. We identified age, Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA), and Glasgow Coma Scale (GCS) score as independent risk factors of RFS, and the combination of GCS and age can improve the AUC of ASPEN to 0.664 (0.620–0.706) for predicting RFS. SNAQ, GLIM, mNICE, and ASPEN do not perform well in identifying neurocritically ill patients at high risk of RFS, although ASPEN appears to have relatively a good validity among them. Combining GCS and age with ASPEN slightly improves RFS recognition, but it still leaves a lot of room for improvement.

Abstract
BACKGROUND Eating disorders (EDs) are potentially severe, complex, and life-threatening illnesses. The mortality rate of EDs is significantly elevated compared to other psychiatric conditions, primarily due to medical complications and suicide. The current rapid review aimed to summarise the literature and identify gaps in knowledge relating to any psychiatric and medical comorbidities of eating disorders. METHODS This paper forms part of a rapid review) series scoping the evidence base for the field of EDs, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for English-language studies focused on the psychiatric and medical comorbidities of EDs, published between 2009 and 2021. High-level evidence such as meta-analyses, large population studies and Randomised Control Trials were prioritised. RESULTS A total of 202 studies were included in this review, with 58% pertaining to psychiatric comorbidities and 42% to medical comorbidities. For EDs in general, the most prevalent psychiatric comorbidities were anxiety (up to 62%), mood (up to 54%) and substance use and post-traumatic stress disorders (similar comorbidity rates up to 27%). The review also noted associations between specific EDs and non-suicidal self-injury, personality disorders, and neurodevelopmental disorders. EDs were complicated by medical comorbidities across the neuroendocrine, skeletal, nutritional, gastrointestinal, dental, and reproductive systems. Medical comorbidities can precede, occur alongside or emerge as a complication of the ED. CONCLUSIONS This review provides a thorough overview of the comorbid psychiatric and medical conditions co-occurring with EDs. High psychiatric and medical comorbidity rates were observed in people with EDs, with comorbidities contributing to increased ED symptom severity, maintenance of some ED behaviours, and poorer functioning as well as treatment outcomes. Early identification and management of psychiatric and medical comorbidities in people with an ED may improve response to treatment and overall outcomes.

Abstract
PURPOSE Abnormalities in autonomic function have been observed in people with anorexia nervosa. However, the majority of investigations have utilised heart rate variability as the sole assessment of autonomic activity. The current study utilised a variety of methodologies to assess autonomic nervous system function in women with a current diagnosis of anorexia, a past diagnosis of anorexia who were weight-restored, and healthy controls. METHODS The sample included 37 participants: 10 participants with anorexia, 17 weight-restored participants (minimum body mass index > 18.5 for minimum of 12 months) and 10 controls. Assessments of autonomic function included muscle sympathetic nerve activity (MSNA) using microneurography, heart rate variability, baroreflex sensitivity, blood pressure variability, head-up tilt table test, sudomotor function and assessment of plasma catecholamines. RESULTS MSNA (bursts/min) was significantly decreased in both anorexia (10.22 ± 6.24) and weight-restored (17.58 ± 1.68) groups, as compared to controls (23.62 ± 1.01, p < 0.001 and p = 0.033, respectively). Participants with anorexia had a significantly lower standard deviation in heart rate, lower blood pressure variability and decreased sudomotor function as compared to controls. Weight-restored participants demonstrated decreased baroreflex sensitivity in response to head-up tilt as compared to controls. CONCLUSION Women with a current or previous diagnosis of anorexia have significantly decreased sympathetic activity, which may reflect a physiological response to decreased energy intake. During the state of starvation, women with anorexia also displayed decreased sudomotor function. The consequences of a sustained decrease in MSNA are unknown, and future studies should investigate autonomic function in long-term weight-restored participants to determine whether activity returns to normal.

Abstract
In hospitals through Europe and worldwide, the practices regarding hospital diets are very heterogeneous. Hospital diets are rarely prescribed by physicians, and sometimes the choices of diets are based on arbitrary reasons. Often prescriptions are made independently from the evaluation of nutritional status, and without taking into account the nutritional status. Therapeutic diets (low salt, gluten-free, texture and consistency modified, …) are associated with decreased energy delivery (i.e. underfeeding) and increased risk of malnutrition. The European Society for Clinical Nutrition and Metabolism (ESPEN) proposes here evidence-based recommendations regarding the organization of food catering, the prescriptions and indications of diets, as well as monitoring of food intake at hospital, rehabilitation center, and nursing home, all of these by taking into account the patient perspectives. We propose a systematic approach to adapt the hospital food to the nutritional status and potential food allergy or intolerances. Particular conditions such as patients with dysphagia, older patients, gastrointestinal diseases, abdominal surgery, diabetes, and obesity, are discussed to guide the practitioner toward the best evidence based therapy. The terminology of the different useful diets is defined. The general objectives are to increase the awareness of physicians, dietitians, nurses, kitchen managers, and stakeholders towards the pivotal role of hospital food in hospital care, to contribute to patient safety within nutritional care, to improve coverage of nutritional needs by hospital food, and reduce the risk of malnutrition and its related complications.

Abstract
BACKGROUND The refeeding syndrome has been described as a potentially life-threatening complication of renutrition. However, moving from single reports to larger population studies, the real impact of refeeding syndrome on all-cause mortality is still unknown. METHODS PubMed/Medline, EMBASE, Cochrane library, and CINAHL databases were systematically searched until September 2020 for studies reporting mortality rates in patients who developed the syndrome at renutrition compared with those who did not develop it. Effect sizes were pooled through a random-effect model. RESULTS Thirteen studies were finally considered in the meta-analysis, for a total of 3846 patients (mean age 64.5 years; 58% males). Pooled data showed a nonsignificant trend toward an increased short-term (≤1 month) mortality in patients developing the refeeding syndrome (odds ratio = 1.27, 95% confidence interval 0.93-1.72), mostly driven by studies in which renutrition was not prescribed and supervised by a nutritional support team (P = .01 at subgroup analysis) and by studies published in previous years (P = .04 at meta-regression). When examining medium-term (≤6 month) mortality, an overall statistical significance toward higher risk was observed (odds ratio = 1.54, 95% confidence interval 1.04-2.28). CONCLUSION This was the first meta-analysis that specifically assessed the impact of refeeding syndrome on mortality. Our results suggested a nonsignificant trend toward increased mortality in the short term but a significantly increased mortality in the medium term. The supervision/management of the refeeding process by a nutrition specialist might be a key factor for the limitation of this mortality excess.

Abstract
Background: Autonomic nervous system (ANS) dysfunction has been suggested to contribute to the high prevalence of cardiovascular complications in individuals with anorexia nervosa (AN), yet has not been thoroughly investigated. The current review aimed to synthesize the evidence of basal ANS function in individuals with a current diagnosis of AN and those with a previous diagnosis who had achieved weight restoration, as compared to controls. Methods: A systematic review of nine databases was conducted and studies that were published in a peer-review journal, in English, that included at least one assessment of ANS function in individuals with a current or previous diagnosis of AN were selected. Forty-six studies were included with a total of 811 participants with a current diagnosis of AN and 123 participants with a previous diagnosis of AN. Results: ANS function was assessed through heart rate variability (n = 27), orthostatic challenge, blood pressure variability or baroreflex sensitivity (n = 11), adrenergic activity (n = 14), skin conductance level (n = 4), and pupillometry (n = 1). Individuals with AN demonstrated increased parasympathetic activity and decreased sympathetic activity, suggestive of autonomic dysregulation. Following weight restoration, autonomic function trended toward, or was equivalent to, control levels. Discussion: Autonomic dysregulation is indicated through a range of assessments in individuals with AN. Future investigations should utilize a variety of assessments together in order to conclusively establish the nature of autonomic dysfunction in AN, and following extended weight restoration. Moreover, investigation into the co-occurrence of ANS function and cardiovascular risk is required.

Clin Nutr 2021; 40:3688-3701.

Abstract
BACKGROUND & AIMS The refeeding syndrome (RFS) has been recognized as a potentially life-threatening metabolic complication of re-nutrition, but the definition widely varies and, its incidence is unknown. The aim of this systematic review and meta-analyses was to estimate the incidence of RFS in adults by considering the definition used by the authors as well as the recent criteria proposed by the American Society of Parenteral and Enteral Nutrition (ASPEN) consensus. Furthermore, the incidence of refeeding hypophosphatemia (RH) was also assessed. METHODS Four databases were systematically searched until September 2020 for retrieving trials and observational studies. The incidences of RFS and RH were expressed as percentage and reported with 95% confidence intervals (CI). RESULTS Thirty-five observational studies were included in the analysis. The risk of bias was serious in 16 studies and moderate in the remaining 19. The incidence of RFS varied from 0% to 62% across the studies. No substantial change in the originally reported incidence of RFS was found by applying the ASPEN criteria. Similarly, the incidence of RH ranged between 7% and 62%. In the subgroup analyses, inpatients from Intensive Care Units (ICUs) and those initially fed with >20 kcal/kg/day seemed to have a higher incidence of both RFS (pooled incidence = 44%; 95% CI 36%-52%) and RH (pooled incidence = 27%; 95% CI 21%-34%). However, due to the high heterogeneity of data, summary incidence measures are meaningless. CONCLUSION The incidence rate of both RFS and RH greatly varied according to the definition used and the population analyzed, being higher in ICU inpatients and in those with increased initial caloric supply. Therefore, a universally accepted definition for RFS, taking different clinical contexts and groups of patients into account, is still needed to better characterize the syndrome and its approach.

Abstract
The Refeeding Syndrome (RFS) is a potentially serious, but still overlooked condition, occurring in individuals who are rapidly fed after a period of severe undernourishment. RFS derives from an abnormal electrolyte and fluid shifts leading to many organ dysfunctions. Symptoms generally appear within 2-5 days of re-feeding and may be absent/mild or severe and life threating, depending on the pre-existing degree of malnutrition and comorbidities. The lack of a standard definition and the nonspecificity of the symptoms make both incidence estimate and diagnosis difficult. In 2020, the American Society for Parenteral and Enteral Nutrition (ASPEN) proposed a unifying definition for the RFS and its severity classification. The awareness of the condition is crucial for identifying patients at risk, preventing its occurrence, and improving the management. The objectives of this narrative review were to summarize the current knowledge and recommendations about the RFS and to provide useful tips to help physicians to recognize and prevent the syndrome.

Abstract
OBJECTIVES To determine the incidence of refeeding syndrome in otherwise healthy children <3 years of age admitted for failure to thrive (FTT). METHODS A multicenter retrospective cohort study was performed on patients aged ≤36 months admitted with a primary diagnosis of FTT from January 1, 2011, to December 31, 2016. The primary outcome measure was the percentage of patients with laboratory evidence of refeeding syndrome. Exclusion criteria included admission to an ICU, parenteral nutrition, history of prematurity, gastrostomy tube feeds, and any complex chronic conditions. RESULTS Of the 179 patients meeting inclusion criteria, none had laboratory evidence of refeeding syndrome. Of these, 145 (81%) had laboratory work done at the time of admission, and 69 (39%) had laboratory work repeated after admission. A small percentage (6%) of included patients experienced an adverse event due to repeat laboratory draw. CONCLUSIONS In otherwise healthy hospitalized patients <3 years of age with a primary diagnosis of FTT, routine laboratory monitoring for electrolyte derangements did not reveal any cases of refeeding syndrome. More robust studies are needed to determine the safety and feasibility of applying low-risk guidelines to this patient population to reduce practice variability and eliminate unnecessary laboratory evaluation and monitoring.

Hypophosphatemia in critically ill adults and children - A systematic review. Clin Nutr 2020; 40:1744-1754.

Abstract
BACKGROUND & AIMS Phosphate is the main intracellular anion essential for numerous biological processes. Symptoms of hypophosphatemia are non-specific, yet potentially life-threatening. This systematic review process was initiated to gain a global insight into hypophosphatemia, associated morbidity and treatments. METHODS A systematic review was conducted (PROSPERO CRD42020163191). Nine clinically relevant questions were generated, seven for adult and two for pediatric critically ill patients, and prevalence of hypophosphatemia was assessed in both groups. We identified trials through systematic searches of Medline, EMBASE, Scopus, Cochrane Central Register of Controlled Trials, CINAHL, and Web of Science. Quality assessment was performed using the Cochrane risk of bias tool for randomized controlled trials and the Newcastle-Ottawa Scale for observational studies. RESULTS For all research questions, we identified 2727 titles in total, assessed 399 full texts, and retained 82 full texts for evidence synthesis, with 20 of them identified for several research questions. Only 3 randomized controlled trials were identified with two of them published only in abstract form, as well as 28 prospective and 31 retrospective studies, and 20 case reports. Relevant risk of bias regarding selection and comparability was identified for most of the studies. No meta-analysis could be performed. The prevalence of hypophosphatemia varied substantially in critically ill adults and children, but no study assessed consecutive admissions to intensive care. In both critically ill adults and children, several studies report that hypophosphatemia is associated with worse outcome (prolonged length of stay and the need for respiratory support, and higher mortality). However, there was insufficient evidence regarding the optimal threshold upon which hypophosphatemia becomes critical and requires treatment. We found no studies regarding the optimal frequency of phosphate measurements, and regarding the time window to correct hypophosphatemia. In adults, nutrient restriction on top of phosphate repletion in patients with refeeding syndrome may improve survival, although evidence is weak. CONCLUSIONS Evidence on the definition, outcome and treatment of clinically relevant hypophosphatemia in critically ill adults and children is scarce and does not allow answering clinically relevant questions. High quality clinical research is crucial for the development of respective guidelines.

Abstract
BACKGROUND AND AIMS The clinical nutrition-eating disorders-unit in Raymond Poincaré Hospital is a reference center for the management of severe malnutrition and its complications in patients with anorexia nervosa (AN). The purpose of this study is to specify socio-demographic, anamnesic and clinical characteristics of AN patients hospitalized for extreme malnutrition, to identify types and prevalence of medical complications presented during their hospitalization for refeeding and the evolution of patients nutritional status. METHODS Demographic, clinical and paraclinical data of 354 severely malnourished AN patients were collected, during their first hospitalization in the unit, between November 1997 and January 2014, through medical records. The prevalence of medical complications was compared between the 2 AN subtypes (restricting and binging-purging). RESULTS 339 patients were female and mean age was 28.7 ± 10.7 years old. Duration of AN was 9.5 ± 9 years, 173 (48.9%) patients had a restricting AN subtype. BMI at admission was 12.2 ± 1.6 kg/m2, 280 (79.3%) patients had already been hospitalized for AN in other hospitals before. Psychiatric comorbidities were present in 168 (47.5%) patients. Associated somatic comorbidities concerned 70 (19.8%) patients. Outcomes during hospitalization were marked by 4.1 ± 3.9 kg weight gain on 36.9 ± 30.5 days. Enteral nutrition was provided in 304 (85.9%) patients. Main medical complications during hospitalization were: anemia (79%), neutropenia (53.9%), hypertransaminasemia (53.7%), osteoporosis (46.3%), hypokalemia (39.5%), hypophosphatemia (26%), hypoglycemia (13.8%), infectious complications (24.3%), cardiac dysfunction (7.1%), and proven gelatinous bone marrow transformation (6.5%). Hypokalemia was more frequent in binging-purging subtype. Lympho-neutropenia and hypertransaminasemia were more frequent in restricting subtype. During their hospitalization, 35 (10%) patients were referred to medical intensive care unit and 5 patients died. CONCLUSIONS AN patients hospitalized for severe malnutrition in a specialized clinical nutrition unit have severe and frequent medical complications. Psychiatric comorbidities are also frequent and could complicate medical care. A specialized and multidisciplinary management of these patients is therefore essential.

Abstract
BACKGROUND & AIMS Although refeeding syndrome (RFS) has been recognized as a potentially fatal metabolic complication, the definition of RFS has remained unclear. Recently, European researchers suggested an evidence-based and consensus-supported algorithm that consisted of a new RFS risk classification and treatment strategies for medical inpatients. The classification was based on the National Institute for Health and Clinical Excellence (NICE) criteria for patients at risk of developing RFS. In this study, we aimed to investigate the frequency of each applied new risk group and the association between the new classification and mortality in critically ill patients. METHODS This cohort study was conducted at a Japanese metropolitan tertiary-care university hospital from December 2016 to December 2018. We included critically ill adult patients who were admitted to the intensive care unit (ICU) via the emergency department and who stayed in the ICU for 24 h or longer. We applied the new risk classification based on the NICE RFS risk factors on ICU admission. The main exposure was risk classification of RFS: no risk, low risk, high risk, or very high risk. The primary outcome was in-hospital mortality censored at day 30 after ICU admission. We performed a multivariable analysis using Cox proportional hazard regression. RESULTS We analyzed 542 patients who met the eligibility criteria. The prevalence of the four RFS risk classification groups was 25.8% for no risk, 25.7% for low risk, 46.5% for high risk, and 2.0% for very high risk. The 30-day mortality was 5.0%, 7.2%, 16.3%, and 27.3%, respectively (log-rank trend test: p < 0.001). In the multivariable Cox regression, adjusted hazard ratios with no risk group as a reference were 1.28 (95% CI 0.48-3.38) for low risk, 2.81 (95% CI 1.24-6.35) for high risk, and 3.17 (95% CI 0.78-12.91) for very high risk. CONCLUSIONS Approximately half the critically ill patients were categorized as high or very high risk based on the new risk classification. Furthermore, as the risk categories progressed, the 30-day in-hospital mortality increased. Early recognition of patients at risk of developing RFS may improve patient outcomes through timely and optimal nutritional treatment.

Abstract
Refeeding syndrome (RFS) is the metabolic response to the switch from starvation to a fed state in the initial phase of nutritional therapy in patients who are severely malnourished or metabolically stressed due to severe illness. It is characterized by increased serum glucose, electrolyte disturbances (particularly hypophosphatemia, hypokalemia, and hypomagnesemia), vitamin depletion (especially vitamin B1 thiamine), fluid imbalance, and salt retention, with resulting impaired organ function and cardiac arrhythmias. The awareness of the medical and nursing staff is often too low in clinical practice, leading to under-diagnosis of this complication, which often has an unspecific clinical presentation. This review provides important insights into the RFS, practical recommendations for the management of RFS in the medical inpatient population (excluding eating disorders) based on consensus opinion and on current evidence from clinical studies, including risk stratification, prevention, diagnosis, and management and monitoring of nutritional and fluid therapy.

Abstract
BACKGROUND Anorexia Nervosa (AN) is a psychiatric disorder characterised by a physical and psychosocial deterioration due to an altered pattern on the intake and weight control. The severity of the disease is based on the degree of malnutrition. The objective of this article is to review the scientific evidence of the refeeding process of malnourished inpatients with AN; focusing on the clinical outcome. METHODS We conducted an extensive search in Medline and Cochrane; on April 22; 2019; using different search terms. After screening all abstracts; we identified 19 papers that corresponded to our inclusion criteria. RESULTS The article focuses on evidence on the characteristics of malnutrition and changes in body composition; energy and protein requirements; nutritional treatment; physical activity programmes; models of organisation of the nutritional treatment and nutritional support related outcomes in AN patients. CONCLUSION Evidence-based standards for clinical practice with clear outcomes are needed to improve the management of these patients and standardise the healthcare process.

The use of enteral nutrition in the treatment of eating disorders: a systematic review. Eat Weight Disord 2019; 24:179-198. [PMID: 30196528 DOI: 10.1007/s40519-018-0572-4] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Accepted: 08/27/2018] [Indexed: 02/06/2023] Open
Abstract
PURPOSE Enteral nutrition (EN) is frequently used in the treatment of anorexia nervosa (AN), and less commonly, bulimia nervosa (BN); yet, no standardized guidelines for treatment exist at this time. The aim of this review is to investigate the efficacy of EN in the treatment of eating disorders and make recommendations for clinical practice and future research. METHODS An exhaustive literature search of 7 databases was completed. The search strategy combined key terms anorexia nervosa, bulimia, and eating disorders with terms associated with EN. There were no restrictions on publication date or language. Studies that assessed the effect of EN on weight restoration, refeeding syndrome, and binge/purge behaviors in the treatment of AN and BN were included. RESULTS Of 73 full-text articles reviewed, 22 met inclusion criteria. Nineteen studies reported that significant short-term weight gain was achieved when EN was used for refeeding malnourished AN patients; however, results varied for the six studies reporting on long-term weight gain, maintenance, and recovery. In studies with a comparator, no significant differences were found between the EN and oral refeeding cohorts regarding gastrointestinal disturbance, refeeding syndrome, or electrolyte abnormalities. Five studies examined the effect of EN on binge/purge behaviors, suggesting that temporary exclusive EN decreases the frequency and severity of binge/purge episodes. CONCLUSION Although EN is an essential life-saving treatment in severe cases of AN, it does not guarantee long-term success or recovery. The results of this systematic review highlight the need for prospective controlled trials with adequate sample sizes to make comparisons between specific feeding methods, formulations, and defined short and long-term outcomes. Evidence-based standards for clinical practice are needed with specific guidelines for best results for AN and BN treatment. LEVEL OF EVIDENCE I, systematic review.

Abstract
Anorexia nervosa is a syndrome, that is collections of symptoms, which is not defined by its etiology. The severe cases are intractable. The syndrome is associated with multiple, profound endocrine alterations which may be adaptive, reactive or etiologic. Adaptive changes potentially may be inappropriate in clinical settings such as inpatient intensive re-nutrition or in a setting with somatic comorbidity. Electrolyte levels must be closely monitored during the refeeding process, and the need for weight gain must be balanced against potentially fatal refeeding complications. An important focus of clinical research should be to identify biomarkers associated with different stages of weight loss and re-nutrition combined with psychometric data. Besides well-established peripheral endocrine actions, several hormones also are released directly to different brain areas, where they may exert behavioral and psychogenic actions that could offer therapeutic targets. We need reliable biomarkers for predicting outcome and to ensure safe re-nutrition, however, first of all we need them to explore the metabolism in anorexia nervosa to open new avenues with therapeutic targets. A breakthrough in our understanding and treatment of this whimsical disease remains. Considering this, the aim of the present review is to provide an updated overview of the many endocrine changes in a clinical perspective.

Abstract
Aging is linked to physiological and pathophysiological changes. In this context, elderly patients often are frail, which strongly correlates with negative health outcomes and disability. Elderly patients are often malnourished, which again is an independent risk factor for both frailty and adverse clinical outcomes. Malnutrition and resulting frailty can be prevented by adequate nutritional interventions. Yet, use of nutritional therapy can also have negative consequences, including a potentially life-threatening metabolic alteration called refeeding syndrome (RFS) in high-risk patients. RFS is characterized by severe electrolyte shifts (mainly hypophosphatemia, hypomagnesemia and hypokalemia), vitamin deficiency (mainly thiamine), fluid overload and salt retention leading to organ dysfunction and cardiac arrhythmias. Although the awareness of malnutrition among elderly people is well established, the risk of RFS is often neglected, especially in the frail elderly population. This partly relates to the unspecific clinical presentation and laboratory changes in the geriatric population. The aim of this review is to summarize recently published recommendations for the management of RFS based on current evidence from clinical studies adapted with a focus on elderly patients.

A Higher-Calorie Refeeding Protocol Does Not Increase Adverse Outcomes in Adult Patients with Eating Disorders. J Acad Nutr Diet 2018; 118:1450-1463. [PMID: 29656932 DOI: 10.1016/j.jand.2018.01.023] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2017] [Accepted: 01/30/2018] [Indexed: 10/17/2022]
Abstract
BACKGROUND Patients with eating disorders (EDs) are often considered a high-risk population to refeed. Current research advises using "start low, go slow" refeeding methods (∼1,000 kcal/day, advancing ∼500 kcal/day every 3 to 4 days) in adult patients with severe EDs to prevent the development of refeeding syndrome (RFS), typically characterized by decreases in serum electrolyte levels and fluid shifts. OBJECTIVE To compare the incidence of RFS and related outcomes using a low-calorie protocol (LC) (1,000 kcal) or a higher-calorie protocol (HC) (1,500 kcal) in medically compromised adult patients with EDs. DESIGN This was a retrospective pre-test-post-test study. PARTICIPANTS/SETTING One hundred and nineteen participants with EDs, medically admitted to a tertiary hospital in Brisbane, Australia, between December 2010 and January 2017, were included (LC: n=26, HC: n=93). The HC refeeding protocol was implemented in September 2013. MAIN OUTCOME MEASURES Differences in prevalence of electrolyte disturbances, hypoglycemia, edema, and RFS diagnoses were examined. STATISTICAL ANALYSIS PERFORMED χ2 tests, Kruskal-Wallis H test, analysis of variance, and independent t tests were used to compare data between the two protocols. RESULTS Descriptors were similar between groups (LC: 28±9 years, 96% female, 85% with anorexia nervosa, 31% admitted primarily because of clinical symptoms of exacerbated ED vs HC: 27±9 years, 97% female, 84% with anorexia nervosa, 44% admitted primarily because of clinical symptoms of exacerbated ED, P>0.05). Participants refed using the LC protocol had higher incidence rates of hypoglycemia (LC: 31% vs HC: 10%, P=0.012), with no statistical or clinical differences in electrolyte disturbances (LC: 65% vs HC: 45%, P=0.079), edema (LC: 8% vs HC: 6%, P=0.722) or diagnosed RFS (LC: 4% vs HC: 1%, P=0.391). CONCLUSIONS A higher-calorie refeeding protocol appears to be safe, with no differences in rates of electrolyte disturbances or clinically diagnosed RFS and a lower incidence of hypoglycemia. Future research examining higher-calorie intakes, similar to those studied in adolescent patients, may be beneficial.

Abstract
PURPOSE OF REVIEW To summarize recent relevant studies regarding refeeding syndrome (RFS) in critically ill patients and provide recommendations for clinical practice. RECENT FINDINGS Recent knowledge regarding epidemiology of refeeding syndrome among critically ill patients, how to identify ICU patients at risk, and strategies to reduce the potential negative impact on outcome are discussed. SUMMARY RFS is a potentially fatal acute metabolic derangement that ultimately can result in marked morbidity and even mortality. These metabolic derangements in ICU patients differ from otherwise healthy patients with RFS, as there is lack of anabolism. This is because of external stressors inducing a hypercatabolic response among other reasons also reflected by persistent high glucagon despite initiation of feeding. Lack of a proper uniform definition complicates diagnosis and research of RFS. However, refeeding hypophosphatemia is commonly encountered during critical illness. The correlations between risk factors proposed by international guidelines and the occurrence of RFS in ICU patients remains unclear. Therefore, regular phosphate monitoring is recommended. Based on recent trials among critically ill patients, only treatment with supplementation of electrolytes and vitamins seems not sufficient. In addition, caloric restriction for several days and gradual increase of caloric intake over days is recommendable.

Abstract
CONTEXT Although hypophosphatemia is usually very seldom, it can reach two to 3% of hospitalized patients and until 28% of intensive care unit patients. Due to the lack of knowledge, clinical practice regarding seeking or treatment of hypophosphatemia is very heterogenous. However its clinical consequences might be heavy. A better knowledge of its causes, physiopathological effects and treatment should lead to a documented and homogenous care of these patients in clinics. OBJECTIVE The aim of our study was a systematic review of littérature, seeking for publications about causes, consequences and treatment of hypophosphatemia. DOCUMENTARY SOURCES (KEYWORDS AND LANGUAGE) A research has been conducted on the Medline database by using the following keywords "phosphorus supplementation", "hypophosphatemia" and ("physiopathology" or "complications"). RESULTS Three mains mechanisms might be responsible for hypophosphatemia: a decrease in digestive absorption, a rise in kidney excretion and a transfer of phosphorus to the intracellular compartment. Denutrition, acid base balance troubles, parenteral nutrition or several drugs are capable of provoking or favouring hypophosphatemia. All these situations are frequently encountered in intensive care unit. Consequences of hypophosphatemia might be serious. Best studied and documented are cardiac and respiratory muscle contractility decrease, sometimes leading to acute cardiac and respiratory failure, cardiac rhythm troubles and cardiac arrest. Hypophosphatemia is frequent during sepsis. It could be responsible for leucocyte dysfunction that might favour or increase sepsis. The treatment of hypophosphatemia is usually simple through a supplementation that quickly restores a regular concentration, with few adverse effects when regularly used. CONCLUSION During at-risk situations, the systematic search for hypophosphatemia and its treatment may limit the occurrence of serious consequences.

Abstract
OBJECTIVES Refeeding syndrome (RFS) can be a life-threatening metabolic condition after nutritional replenishment if not recognized early and treated adequately. There is a lack of evidence-based treatment and monitoring algorithm for daily clinical practice. The aim of the study was to propose an expert consensus guideline for RFS for the medical inpatient (not including anorexic patients) regarding risk factors, diagnostic criteria, and preventive and therapeutic measures based on a previous systematic literature search. METHODS Based on a recent qualitative systematic review on the topic, we developed clinically relevant recommendations as well as a treatment and monitoring algorithm for the clinical management of inpatients regarding RFS. With international experts, these recommendations were discussed and agreement with the recommendation was rated. RESULTS Upon hospital admission, we recommend the use of specific screening criteria (i.e., low body mass index, large unintentional weight loss, little or no nutritional intake, history of alcohol or drug abuse) for risk assessment regarding the occurrence of RFS. According to the patient's individual risk for RFS, a careful start of nutritional therapy with a stepwise increase in energy and fluids goals and supplementation of electrolyte and vitamins, as well as close clinical monitoring, is recommended. We also propose criteria for the diagnosis of imminent and manifest RFS with practical treatment recommendations with adoption of the nutritional therapy. CONCLUSION Based on the available evidence, we developed a practical algorithm for risk assessment, treatment, and monitoring of RFS in medical inpatients. In daily routine clinical care, this may help to optimize and standardize the management of this vulnerable patient population. We encourage future quality studies to further refine these recommendations.

Throw caution to the wind: is refeeding syndrome really a cause of death in acute care? Eur J Clin Nutr 2017; 72:93-98.

Abstract
BACKGROUND/OBJECTIVES Refeeding syndrome (RFS), a life-threatening medical condition, is commonly associated with acute or chronic starvation. While the prevalence of patients at risk of RFS in hospital reportedly ranges from 0 to 80%, the prevalence and types of patients who die as a result of RFS is unknown. We aimed to measure the prevalence rate and examine the case histories of patients who passed away with RFS listed as a cause of death. SUBJECTS/METHODS Patients were eligible for inclusion provided their death occurred within a Queensland hospital. Medical charts were reviewed, for medical, clinical and nutrition histories with results presented using descriptive statistics. RESULTS Across 18 years (1997-2015) and ~260000 hospital deaths, five individuals (4F, 74 (37-87)yrs) were identified. No patient had a past or present diagnosis, such as anorexia nervosa, that would classify them as at high risk for RFS. RFS was not listed as the primary cause of death for any patient. No individual consumed >3400 kJ per day. Limited consensus was observed in the signs and symptoms used to diagnose RFS, although all patients experienced low levels of potassium, phosphate and/or magnesium. Eighty percent of electrolytes improved before death. CONCLUSIONS RFS was a rare underlying cause of death, despite reported high prevalence rates of risk. Patient groups usually considered to be at high risk were not identified, suggesting a level of imprecision with the interpretation of criteria used to identify RFS risk. More detailed research is warranted to assist in the identification of those distinctly at risk of RFS.

Abstract
PURPOSE Anorexia nervosa (AN) is a severe pathology on account of the high levels of associated morbidity and mortality. This study aimed to assess whether time in somatic intensive care unit, justified by a patient's somatic condition in the course of hospital care, has any relationship with patient outcome in terms of mortality in the long term. METHODS 195 patients were hospitalised for AN between April 1996 and May 2002, 97 were re-assessed 9 years later on average. RESULTS Out of 195 patients hospitalised for AN between April 1996 and May 2002, 29 had required transfer to intensive care. Mortality at 9 years was 20 times higher in the group having been transferred to intensive care, irrespective of the duration of follow-up. CONCLUSION The clinical seriousness of the somatic condition during hospitalisation for AN is a risk factor for excess mortality in the medium term.

Abstract
BACKGROUND & AIMS Objective evidence about the risks associated with anorexia nervosa and how to manage them, is limited. The aim of this study is to describe the medical risk profile, management and outcomes of a cohort of patients with severe anorexia nervosa (sAN) during medical stabilisation treatment. METHODS Retrospective analysis of case records gathered medical risk data for a 90 day high risk period, on 65 patients with sAN admitted to two specialist services. Prospectively established definitions of medical risk variables and significant complications were applied to the data to describe the risk profiles and outcomes. RESULTS Amongst this population with an average initial BMI of 12.8 kg/m2, 74% developed no significant medical complications. Oral re-feeding over 60 days achieved an increase in mean BMI to 14.4 kg/m2 and mean weight gain of 4 kg. No patients developed severe hypophosphatemia (<0.45 mmol/L) or any other indicators of a re-feeding syndrome. All the medical complications that arose were temporary. CONCLUSIONS Initial re-feeding and medical stabilisation of patients with severe AN can be managed safely in specialist inpatient and community settings with slow re-feeding. Although the prevalence of complications was shown to be low, slight worsening of medical risk markers and increased incidence of complications did occur during initial re-feeding. The limited comparable published data appears to support slower rates of re-feeding, showing fewer abnormal results and complications. There is however a need for a definitive prospective multi-centre observational cohort study to investigate risks factors, and the effects of treatment on medical outcomes, in a large sample with varied rates of re-feeding.

Abstract
BACKGROUND Refeeding syndrome (RFS) is an important and well-known complication in malnourished patients, but the incidence of RFS after obesity surgery is unknown and the awareness of RFS in obese patients as a postsurgical complication must be raised. We present a case of RFS subsequent to biliopancreatic diversion in a morbidly obese patient. CASE REPORT A 48-year-old female patient with a BMI of 41.5 kg/m2 was transferred to our hospital due to Wernicke's Encephalopathy in a global malabsorptive syndrome after biliopancreatic diversion. Parenteral nutrition, vitamin supplementation and high-dosed intravenous thiamine supplementation were initiated. After 14 days, the patient started to develop acute respiratory failure, and neurological functions were impaired. Blood values showed significant electrolyte disturbances. RFS was diagnosed and managed according to the NICE guidelines. After 14 days, phosphate levels had returned to normal range, and neurological symptoms were improved. CONCLUSION Extreme weight loss following obesity surgery has been shown to be associated with undernutrition. These patients are at high risk for evolving RFS, even though they may still be obese. Awareness of RFS as a postsurgical complication, the identification of patients at risk as well as prevention and correct management should be routinely performed at every bariatric center.

Abstract
During refeeding syndrome-a well-known and dreaded complication of weight-restauration in anorexia nervosa-a shift of electrolytes and fluid can occur in malnourished patients and might therefore lead to-potentially fatal-cardiovascular, respiratory and neurological symptoms. Causes of this are metabolic and hormonal changes during re-establishment of a carbohydrate-rich diet. This syndrome is most commonly associated with hypophosphatemia, which can however be accompanied by other chemical laboratory abnormalities. Standardized guidelines for the prevention and management of the refeeding syndrome have not yet been established. In case and cohort studies different low- and high-calorie diet protocols led to comparable results with similar complication rates. A focus should be placed on prevention of serious complications by careful monitoring. The pathophysiology, the main constituents in the development of the refeeding syndrome, recommendations for risk assessment and treatment, and current evidence are discussed.

Abstract
OBJECTIVE Hypophosphatemia of refeeding is one of the most dangerous complications seen during the treatment of patients with anorexia nervosa. Although easily detectable and treatable, hypophosphatemia is under-recognized as a complication of refeeding. Specific risk factors for the development of hypophosphatemia are likely to exist among patients with severe anorexia nervosa. The purpose of this study was to identify clinically useful markers that may predict the development of or protection from hypophosphatemia during refeeding. METHODS We conducted a retrospective case-control study of 123 patients with severe anorexia nervosa admitted for medical stabilization at the ACUTE Center for Eating Disorders between October 1, 2008 and December 31, 2013. Risk factors for refeeding hypophosphatemia were determined by multivariate logistic regression from clinical parameters and laboratory values measured at the time of admission. RESULTS The prevalence of hypophosphatemia was 33.3% (41 of 123 patients). Higher hemoglobin was the only risk factor associated with a higher odds of developing hypophosphatemia (adjusted odds ratio [aOR], 1.56 [95% confidence interval [CI], 1.12-2.18]). Statistically significant protective factors against the development of hypophosphatemia were observed with higher body mass index (aOR, 0.54 [95% CI, 0.39-0.75]), higher serum potassium (aOR, 0.29 [95% CI, 0.14-0.62]), and higher serum prealbumin (aOR, 0.91 [95% CI, 0.84-0.99]). DISCUSSION Four independent factors associated with refeeding hypophosphatemia were identified. Identification of findings which correlate with hypophosphatemia, or the lack thereof, has the potential to facilitate appropriate triage of patients with anorexia nervosa for closer monitoring during refeeding.

Abstract
Gastroenteric tube feeding plays a major role in the management of patients with poor voluntary intake, chronic neurological or mechanical dysphagia or gut dysfunction, and patients who are critically ill. However, despite the benefits and widespread use of enteral tube feeding, some patients experience complications. This review aims to discuss and compare current knowledge regarding the clinical application of enteral tube feeding, together with associated complications and special aspects. We conducted an extensive literature search on PubMed, Embase and Medline using index terms relating to enteral access, enteral feeding/nutrition, tube feeding, percutaneous endoscopic gastrostomy/jejunostomy, endoscopic nasoenteric tube, nasogastric tube, and refeeding syndrome. The literature showed common routes of enteral access to include nasoenteral tube, gastrostomy and jejunostomy, while complications fall into four major categories: mechanical, e.g., tube blockage or removal; gastrointestinal, e.g., diarrhea; infectious e.g., aspiration pneumonia, tube site infection; and metabolic, e.g., refeeding syndrome, hyperglycemia. Although the type and frequency of complications arising from tube feeding vary considerably according to the chosen access route, gastrointestinal complications are without doubt the most common. Complications associated with enteral tube feeding can be reduced by careful observance of guidelines, including those related to food composition, administration rate, portion size, food temperature and patient supervision.

Abstract
One of the main purposes of admission for anorexia nervosa is to manage acute medical conditions related to this condition. Factors associated with in-hospital mortality in anorexia nervosa remain unclear. This study describes the clinical features of anorexia nervosa patients requiring hospitalization in Japan. We analyzed the association between in-hospital mortality and body mass index upon admission using a currently available, nationwide hospital-based database. We identified 669 eligible patients with anorexia nervosa (BMI ≤ 16.5) from 229 hospitals between July and December, 2010. More than 90 % of the patients were female and 100 patients were admitted involuntarily. The average body mass index was 13.1, and the in-hospital mortality rate was 0.7 %. Five patients who died had a BMI under 11, indicating that patients with an extremely low BMI may be likely to die, despite admission.

Abstract
Restoration of weight and nutritional status are key elements in the treatment of anorexia nervosa (AN). This review aims to describe issues related to the caloric requirements needed to gain and maintain weight for short and long-term recovery for AN inpatients and outpatients.We reviewed the literature in PubMed pertaining to nutritional restoration in AN between 1960-2012. Based on this search, several themes emerged: 1. AN eating behavior; 2. Weight restoration in AN; 3. Role of exercise and metabolism in resistance to weight gain; 3. Medical consequences of weight restoration; 4. Rate of weight gain; 5. Weight maintenance; and 6. Nutrient intake.A fair amount is known about overall caloric requirements for weight restoration and maintenance for AN. For example, starting at 30-40 kilocalories per kilogram per day (kcal/kg/day) with increases up to 70-100 kcal/kg/day can achieve a weight gain of 1-1.5 kg/week for inpatients. However, little is known about the effects of nutritional deficits on weight gain, or how to meet nutrient requirements for restoration of nutritional status.This review seeks to draw attention to the need for the development of a foundation of basic nutritional knowledge about AN so that future treatment can be evidenced-based.

Abstract
OBJECTIVE Determine the incidence of refeeding syndrome, defined by the presence of hypophosphatemia in very-low-birth-weight (VLBW) infants with intrauterine growth restriction (IUGR) compared with those without IUGR. STUDY DESIGN In this retrospective cohort study, VLBW infants admitted over a 10-year period (271 IUGR and 1982 non-IUGR) were evaluated for specific electrolyte abnormalities in the first postnatal week. RESULT IUGR infants were significantly more likely to have hypophosphatemia (41% vs 8.9%, relative risk (95% confidence interval: 7.25 (5.45, 9.65)) and severe hypophosphatemia (11.4% vs 1%, 12.06 (6.82, 21.33)) in the first postnatal week. The incidence of hypophosphatemia was significantly associated with the presence of maternal preeclampsia in all VLBW infants (odds ratio (OR): 2.58 (1.96, 3.40)) when controlling for birth weight and gestational age. CONCLUSION Refeeding syndrome occurs in VLBW infants with IUGR and born to mothers with preeclampsia. Close monitoring of electrolytes, especially phosphorus, is warranted in this population.

Abstract
Anorexia nervosa (AN) is a psychiatric disorder that occurs mainly in female adolescents and young women. The obsessive fear of weight gain, critically limited food intake and neuroendocrine aberrations characteristic of AN have both short- and long-term consequences for the reproductive, cardiovascular, gastrointestinal and skeletal systems. Neuroendocrine changes include impairment of gonadotropin releasing-hormone (GnRH) pulsatile secretion and changes in neuropeptide activity at the hypothalamic level, which cause profound hypoestrogenism. AN is related to a decrease in bone mass density, which can lead to osteopenia and osteoporosis and a significant increase in fracture risk in later life. Rates of birth complications and low birth weight may be higher in women with previous AN. The condition is associated with fertility problems, unplanned pregnancies and generally negative attitudes to pregnancy. During pregnancy, women with the condition have higher rates of hyperemesis gravidarum, anaemia and obstetric complications, as well as impaired weight gain and compromised intrauterine foetal growth. It is reported that 80% of AN patients are affected by a cardiac complications such as sinus bradycardia, a prolonged QT interval on electrocardiography, arrythmias, myocardial mass modification and hypotension. A decrease in bone mineral density (BMD) is one of the most important medical consequences of AN. Reduced BMD may subsequently lead to a three- to seven-fold increased risk of spontaneous fractures. Untreated AN is associated with a significant increase in the risk of death. Better detection and sophisticated therapy should prevent the long-term consequences of this disorder. The aims of treatment are not only recovery but also prophylaxis and relief of the long-term effects of this disorder. Further investigations of the long-term disease risk are needed.

Abstract
Anorexia nervosa exhibits one of the highest death rates among psychiatric patients and a relevant fraction of it is derived from undernutrition. Nutritional and medical treatment of extreme undernutrition present two very complex and conflicting tasks: (1) to avoid "refeeding syndrome" caused by a too fast correction of malnutrition; and (2) to avoid "underfeeding" caused by a too cautious refeeding. To obtain optimal treatment results, the caloric intake should be planned starting with indirect calorimetry measurements and electrolyte abnormalities accurately controlled and treated. This article reports the case of an anorexia nervosa young female affected by extreme undernutrition (BMI 9.6 kg/m(2)) who doubled her admission body weight (from 22.5 kg to 44 kg) in a reasonable time with the use of enteral tube feeding for gradual correction of undernutrition. Refeeding syndrome was avoided through a specialized and flexible program according to clinical, laboratory, and physiological findings.
